Frequently asked questions

Is this a subscription?
No. Perspective Photo Fix is a one-time purchase ($7.99). All features and updates are included with no recurring fees.
Does it use the cloud?
No. Every operation runs locally on your Mac using CoreImage with GPU acceleration — no account, subscription, or internet connection is required.
Can it straighten a tilted horizon?
Yes. A rotation slider spanning -45° to +45° levels the horizon, and you can combine it with the 4-corner grid for complete geometric control.
Does it work on scanned documents and whiteboards?
Yes. Auto-Detect snaps the corner handles to detected page or whiteboard edges, and auto-crop removes the empty borders after correction.
What export formats are available?
JPEG, PNG, HEIC, TIFF, WebP, and JPEG 2000 — each with a quality slider, plus a results modal with Show in Finder buttons.
